Now, his son, who is away with the national team at a training camp, has released a statement to clear up any misunderstanding.

"I would like to apologise for the comments made by my father which have been used by both Polish and English media," he said. "I'd like to make it clear that those were the views and opinions of my father and not mine, and although I respect his views I cannot accept them as I find them disrespectful to the club I truly love.

"I have been at Arsenal football club for seven years now and I have always shown my full respect to the club, Arsène Wenger, all the coaching staff, my team mates and the fans. I've always felt that I received great support from the manager and the fans and I am fully focused on getting back to my best.

"I am proud to be a part of Arsenal and I see my future at this great club."
